I have a 3170 running 7.3 snapmirroring volumes shared on vfiler0 to a 3250 running 8.2.1 7-mode. I want to start replicating a volume that needs to be owned by a vfiler on the 3170. Can I do that with the snapmirror service running on vfiler0? Or do I need to create a /etc/snapmirror.conf and all the other setup required inside the vfiler?
